I had an overpayment that I applied to next year's taxes. I expect to be doing quarterly payments. What paperwork do I need to file?

If you are going to be making quarterly estimated tax payments you will need to mail in payment and a payment voucher to the IRS and/or your state. For the IRS payment vouchers click here: https://www.irs.gov/pub/irs-pdf/f1040es.pdf

Please keep a record of when you paid the estimated payment in and for how much, you will need that information for your return next year.
